To all whom z't may concern.'

Be it known that I, CONRAD KNo'IH, .a citizen of the United States, residing at 38 Mertz avenue, Hillside, county kof Union, and State of New Jersey, have invented certain new and useful Improvements in Roll-Winding Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same. f

The present invention relates to a machine for winding a flat strip or strand of metal into adjacent coils to form rolls for |use in roller-bearings.

A machine of this class is shown in U. S, Patent No. 587,582, issued to John W. Hyatt on the 3rd day of August, 1897, in which machine a rotating mandrel is, by means of a movable carriage, drawnbetween a pair of compression-rolls to which theJ strand of metal is supplied and bent upon the mandrel by the4 rolls. y

Heretofore in machines of this class, the carriage has been moved by along screw and the motion of the screw reversed to restore the carriage to its initial point after winding a strand upon the entire length of .the mandrel.

In such machines, the head which contains the com ression-rolls and levers to press them wit any desired force upon the strandy has been projected at right-angles to the side of the mandrel so as to leave a clear space at Athe opposite side for the introduction of the strand to the mandrel.

Such a machine can obviously wind the strand only in one direction', either right or left-hand, as the clear spaceto introduce the' strand lies at only one side of the mandrel.

The clear space has in some machines been provided at the right-hand side of the mandrel, and in others at the left-hand side, and ltwo entire machines were therefore req uired for winding rolls in the two direc. tions.

Rollerfbearin are frequently made in `w.nich""such rig' t and left-hand rolls are arranged alternately within the cang 0f the bearing to obviate any tendency of the rolls to Work endwise, and the product of the two machines for winding right and lefthand colls must necessarily be equal to sup# ply such bearings as described.

If either machine were disabled the other one was necessarily stopped to avoid overproduction of one kind of rolls.

In the present invention the carriage-feeding screw, which is a very expensive element of construction, is replaced by a rack and plnion, and the machine has the roll-forming head arranged in line with the mandrel instead of transverse to the same. It is thus intermediate to the two positions heretofore employed, leaving clear space for introduc- Ing the strand to the mandrel at either the right or left-hand side. Similar guides for leading the strand obliquely to the mandrel are provided in the` clear space at both sides to direct theO strands at a suitable inclination. The present machine can. thus be used for winding right or left-hand coils, Whichever are desired.

The carriage is provided with a chuck and mechanism for rotatingthe same, and such mechanism is made in the present invention of reversible character, so that the mandrel can be rotated to the right or left-hand, as ma be desired.

n the present machine the carriage-feed Means is provided, accessible 'to the op' era'tor near the winding-head of the machine, for'stopping or starting the carriage at any moment or reversing the ydirection of its motion. By these appliances the product-,of the machine is 'increased several fold and its cost very greatly reduced, While it is enabled to wind right -0 1 left-hand rolls which have heretofore required separate machines.

The invention will be understood byn reference to the annexed drawing, in which Figure 1 is aside elevation, and Fig. 2 a plan, with many of the details (shown in other figures) omitted owing to the smallness of the scale. Fig. 2a is a plan of the winding-head at the level of the mandrel; Fig. 2b is a front elevation of the winding mechanism; Fig. 2 is-a perspective view of the removable retaining-roll; and Fi 2d is an elevation of the control-levers. F1g. 3 is a cross section on Fig. 1 adjacent to the left-hand end of the foot N; Fig. 3a is a side elevation -of the steady-rest and its` fixtures as they are adjusted when in proximity to the winding-head D; Fig. 3b is an elevation of the steady-rest and its fixtures when the steady-rest is elevated partly to its working position." F ig. 4 is a side elevation of the parts connected with the steady-rest; and Fig. 5 is a plan of the gearing which moves the steady-rest at one-half the speed of the carriage. carriage taken on line 6-6 in Fig-7, with the bridge-bearing in section at the center f vline; Fig. 6a is a section where hatched, of

the carriage and reverse gears on line :v in Fig. 6; Fig. 7 is a plan of the carriage with the bridge-bearing in section on line" 7-7 in Fig. 6, and the top of the casing removed; Fig. 8 is a side elevation of the reduction gearing for the carriage-feed with the pinion-shaft in sectionl on lineal-2v2 in Fig. 9; and Fig. 9 is an elevation of the same parts viewed from the right-hand end of Fig. 8.

The frame of the machine as shown' in Figs. 1 to 3 inclusive, is built of side-rails A, standards Band B', and intermediate legs 'C having cross-ties C. (Figs. 1 and 3.)

Winding-head. The winding-head as a whole is designated D, and is shown at the left-hand end of thel frame over the standard B.

In the present construction, the compression-levers a a2 which carry the compression-rolls a3 are projected from its base D outward at the end of the machine," in a line 'I 2 and.2, and retaining-rolls c are journaled uponr these yjfeet. At the rear of the rolls c3 guxc'le-rolls'e2 are pivoted, and operate with the rolls el .in guidingthe strand or strip of metal f2 at an inclination to the mandrel, upon which it is wound and com- Fig. 6 is a vertical section of the same, while in Fig. 2 it is shown approaching the mandrel from the right-hand side.

To readily insert the strands in the grooves of the rolls c2 guide-rolls c3 are mounted on removable slides c, which slides support the retaining-rolls close to the edges or fianges of the rolls c2 thus confining the strands between such flanges. The slides c4 are dovetailed into the seats c at opposite sides of the mandrel, and can be readily slipped out of their grooves when fitting the strands to the mandrel and the chuck and then replaced.

In Fig. 2a the end of the strand f2 .is shown bent to enter a hole 7'3 in the nose of the chuck, which holds the strand firmly while it is being Wound upon the mandrel.

An anvil a5 is provided in the path of the strand at each side ofthe base,'upon which the strand may be severed with a coldchisel when the winding is completed.

The fixtures for guiding the strandv are thus duplicated at opposite sides of the mandrel, so that the strand may be wound with right or left-hand .coils b2 as may be 'desired A -by a. leather or chain-belt F to a powerv shaft G in the lower part of the casing.

The power-shaft is connected detachably, bywa friction-clutch J, to the clutch-pulley J; and all the gearing connected therewith may thus be stopped without arresting the motor.

Re/verging 0 f mandrel.

Reducingsgears are connected with this shaft toy rotate a feed-pinion e and reversing-gears connect'the shaft with the chuck b that opemtes the mandrel b. This chuck is mounted upon a, ,chuck-shaft- H upon which a shifting-gear 2 is mounted, and movable by means of a gear-shifter c to reverse the motion of the chuck-shaft. (See Figs. 6 and 7.)

The carrier d for the shifter-fork d is mounted upon a guide-bar d2 (Fig. 7 and the gear-shifter crank c is mounted upon a shaft c having an arm f upon the outer slde of the casing, with a spring-bolt 'g fitted to holes g in the casing to hold the gearing 1n either of its required positions.

To turn the chuck-shaft in one direction,

`the power-s ht provided with .a gear .t0

with the gear 2, as

' adjusted to the mesh with a shifting-gear 2 upon the chuckshaft. To turn the chuck-shaft in the 0pposite direction, the power-shaft is provided with a gear 3 which rotates an intermediate gear 4 adapted to mesh reversibly shown in Fig. 6a.

The shifting of the gear 2 endwise upon 'the chuck-shaft H operates to change the rotation of theI chuck from the right-hand to the left-hand, or vice versa.

It willbe understood that the gears l and 3 are fastened to the power-shaft and turn continuously with said shaft, but the shifting-gear 2 can be moved to engage either the direct or reversibly-moving pinion, or to stand idly between the two in a space marked 4gin Fig. 6.

The rotation of the chuck can thus be reversed by moving the arm f and engaging the s'prlng-bolt with a suitable bolt-hole g.

A rack 7L is'V sustained upon the standards B and legs C parallel` with the motion of the carriage, and close to the same to engage a feed-pinion 'e which vis mounted upon a pinion-shaft K fitted to bearings K upon the carriage.

The reduction-gearing, as shown in Figs. 6 to 9 inclusive is mounted u on` a housing L at one end of the casing i and consists of a worm` j upon the worm-wheel Z -upon a shaft l', which is connected to the pinion-shaft K by changewheels 19,20', p2, which are indicated by dot-ted lines in Figs. 8 and 9, as the showing of these wheels in full li'n'es would conceal their m unting.

A so-.calle frog m is mounted upon a stationary boss m around the worm-wheel shaft Z, which boss projects from the outer side of the housing L to receive the fro and to hold it rigidly in an adjusted position when clamped by the bolt n.

The arm Z2 of the frog carries a gear-stud o* adjustable in a slot o the shaft- Z, the stud o4 and the pinionshaft K are provided with similar ends having feathers n thereon to receive the changewheels interchangeably, which connect the worm-Wheel shaft with the feed-shaft.

The change-wheels are indicated by the dotted lines p, and p2 in Fig. 8, and the adjustability ofP the s tud o4 in the arm. of the frog permits the desired changes to be made in the speed of thecarriage-feed, by varying the rotations of the pinion' and the consequent feed of the carriage, which is thus pitch ofthe strand on the mandrel. l

A bolt 1 serves as well as the bolt n to hold the frog iirmly in its adjusted position.

With the electric motor running at constant speed, the gearing upon the machine can be instantly stopped, or varied in its power-shaft and a.

whee s y.

The clutch M is provided with a shiftinglever g pivoted upon the outer end of the l casing where it contains the reduction-gear, as shown in Figs. 8 and 9, and the upper end of this lever is 'ointed to a `crank-arm upon a shaft 7'. his shaft is shown in ig. 6 extended lengthwise through the casing-and provided with a hand-crank s at its opposite end (nearest the head D) by operating which the `feed may be stopped or started instantly, by moving the clutch M to the right or the left.

Means is provided which enables the operator, without moving from the head of the machine, to stop point in its travel.

This means consists of a hand-lever o attached to the rock-shaft a which lever may be manually moved to operate the frictionclutch J, and an auxiliary-lever a and endless chain :a connected to such auxiliarylever, and operated'by hand-wheels y at the head of the machine, by which the operator can move the lever o to open or close the friction-clutch without leaving his station.

This chain m2 iscarried over pulleys at the ends of the frame, and the shaft of the pulley az nearest the head D has its ends projected outside of the frame, and furnished each with a hand-wheel y by which the chain can be moved. V

The hand-lever o is attached at the bot-tom to the rock-shaft s which governs the clutch J.

The auxiliary lever o` is pivoted to the casing at the top and extends diagonally1 across the lever o to which itis connected' slowl turning" the pulley and the hand- (see Fig. 2d.)

Whenever it is desired the carriage, the hand-wheel'fis'tnrned b the operator to move the lever o which, t rough 'the joint o2, actuates the lever o and retracts the clutch from the pulley J.

The hand-lever o enables the operator to stop or start the carriage when beside it, and the hand-wheels y enable him to exert the same control when standingl at the head of the machine, which thus enables him to supervise the winding'constantly, and to stop the carriage and all its mechanism whenever an emergency arises.

or start the carriage at any Ma/mrel steady-rest.

With relatively small mandrels the Weight ofthe mandrel and its coils causesit to sag and vibrate between its ends as it .lengthens, and a steady-rest t is therefore rovided to follow the movements of the carriage atonehalf the speed ofthe same, which maintains the stead -rest in the middle offthe ace between t e winding-head and the man relchuck, whatever their distance apart..- l'

The steady-rest is hingedto a foot-plate and the bearing u', and operate normally to4 throw the steady-rest downward againsta stop u upon the foot-plate as shown in Fig.

3a the steady-rest has changeable lining! pieces t to t coils of different sizes. A, 4 The pivoted rod of the steady-rest is provided at its ends with dogs 1:,70, which operate with stationary bars fv, 'v' upon the rails A to raise the steady-rest to its operative po- 'sition when the chuck has withdrawn from the .head D. i

`A chain w is carried over guide-pulle s fw at opposite ends of the machine, and t e opposite ends of the upper member of :the chainare attached to the front and rear-,ends of the carriage, as shown in Fig. 1, and at the left-hand end of the casing in Fig. 4. The chain thus moves lengthwise lof the frame at the same rate and direction as the carriage. l

This chain is provided to move the steadyrest to and from the winding-head at half the speed of the carriage so as to always stand midway between the winding-head and the carriage.

l'The Irack k is made to give a reduced motion to the stead -rest by engagement with a pinion hf journa ed'upon the foot-plate N by an arbor pf, (see Figs. 3, 4 and 5),.-which is thedirec't means to move the foot-plate..

A sprocket-wheel y is attached to the 'arbor and meshed with the chain fw whichy propels the carriage. v

The movement of the chain "w with the carriage causes' it to rotate the s rocketwheel y and turn the pinion h in t e rackteeth. The effect is to advance' the arbor and 'foot-plate N at one-'half the speed of t e carriage; just as a roller placed under a "heavy box to lessen the friction movesponly half as far as the box. v

The parts are adjusted so that the steadyrest always stands in the middle of the space between the carriage and the head D, and 1t is turned down out of the Wav when-the carriage moves up to the hea to rstengage the mandrel. i

l The mandrel does not need .thesupport of the steady-rest until vthe chuck has moved a considerable distance from the' windinghead..` Y

The motions of the steady-rest are reshown'r in Fig. 1, the dog c is intercepted first by the uide-bar fv which turns the steady-rest ha f wa up to its operative position as shown in ig. 3b. l

No mere contact of the dog with 'the guidebar could turn therod u morethan one-,quarter of a revolution as shown in Fig. 3b, and the guide-bar 'u' is therefore provided upon the opposite side of the frame to operate ywith the other dog 7c', to give the steady-rest another one-quarter turn as shown in Figs.

3 and 4,v which brings itin position to support the mandrel.

Fig. 3b shows the steady-rest raised onehalfway to its operative position, and thek dog la 1n position to engage with the guidebars/v and turn the steady-rest to its workin ppsition shown in Fig. 4.

he steady-rest requires no attention upon thfpart of the, erator, but is automatically o lowered out oftli'e Way until its services are required, and 1t is then raised into a working n ition where it supports the extended man rel.

The various attachments which have been described above enable one machine to wind either right-hand or left-hand rolls, and enables the operator, from his position near the winding-head, to control substantially yall the movements of the mechanism involved` in the winding operation.
